Dwight Howard and Shaquille O'Neal have seemingly been beefing for years and things got even more personal between the two former Los Angeles Lakers centers this week when they traded some more shots at each other on social media.

Dwight Howard issued a subtle warning to Shaquille O'Neal that if he doesn't keep his name out of his mouth that there will be a showdown.

Shaq and Dwight Howard went back-and-forth on Twitter, as we should probably expect them to do every now and then.
